      Capacitive Discharge. The MSD 6A Digital Ignition features a capacitor which is quickly charged (within one millisecond) to 520-535 volts and stores it until the ignition is triggered. With the Capacitive Discharge design, the voltage sent to the coil is always at full power even at high rpms unlike conventional stock inductive ignitions which requires the coil to store and step up the voltage in between each firing which can result in a loss of power or top end miss.

      More Efficient. Inside the Digital 6A you'll find a high speed RISC micro-controller that constantly monitors and controls every firing. The circuitry has been updated with highly efficient components that help the ignition produce more power while drawing less current. The new Digital 6A delivers well over 530 volts to the coil with up to 135mJ of spark energy for every firing. Increased output combined with MSD's proven multiple spark series is a winning combination.

      Multiple Sparks. The MSD 6A produces full power multiple sparks for each firing of a plug. The number of multiple sparks decrease as your rpm's increase, however the spark series always lasts for 20° of crankshaft rotation. For rpm's above 3,000 there is simply not enough "time" to fire the spark plug multiple times, so there is only one powerful spark.

      Application. The MSD 6A Digital Ignition Module will work on all Mustangs that are equipped with a 12-15 volt electrical system, including 4, 6 or 8-cylinder engines.
